JSON files with strings are not generated

Hello.

It appears that JSON files with strings contained in JavaScript files are not generated by translate.wordpress.org.

For example, for those contained in these files:

https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.4.1/src/modules/multiple-authors/assets/js/sync-author-slug.jsx and the relative https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.4.1/src/assets/js/sync-author-slug.min.js

https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.4.1/src/modules/multiple-authors/assets/js/sync-post-author.jsx and the relative https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.4.1/src/assets/js/sync-post-author.min.js

Thanks.
